Your proposed alignment with doc-available (empty sequence returns false()),
will only be a true alignment if the wording for unparsed-text-available is
change to read:

"The unparsed-text-available function determines whether a call on the
unparsed-text function with identical arguments would return a non-empty string"

(then it aligns with returning a document-node).
But an empty string could be a sucessful fetch of a file - a zero-length text
file, so i still think it should return true().

And after all, what is the point of the function? Surely, it is to avoid raising
an error, so it should only return false() if an error would have occured.
